AMPTE Ion Release Module magnetospheric tracer spacecraft

The German Ion Release Module (IRM) was one of three AMPTE spacecraft launched together on 16 August 1984. In a highly eccentric orbit it released barium and lithium tracer clouds into the solar wind and magnetosphere, enabling direct studies of plasma transport, acceleration, and interactions with the magnetospheric environment.
